850 feet? You can get decompression sickness at, believe it or not, just 20 feet.
600 feet is generally the max for commercial diving, and that requires extensive decompression.
850 feet is for record attempts, not work. I think 1000’ or thereabouts is the world record.
Fair enough. I got claustrophobic at Mammoth Cave, so I tend to stay on top of the water. Surfing/swimming is my jam, not diving.
